-            Zaguán Blade + Zaguán Coder Daemon are two pieces of one whole. Running Blade through zcoderd unlocks its full potential - longer system prompts, more context, better results. Local AI works, but it's limited.
+            Zaguán Blade + zcoderd are built for long-running coding sessions. In our 250-turn benchmark, context compression and selective retrieval reduced token cost by ~31% on average, with higher gains in context-heavy runs. It’s not always cheaper in lean sessions — it’s designed to prevent context bloat when history grows.
